EDEN PRAIRIE, Minn. -- Vikings quarterback Josh Freeman has concussion-like symptoms, head coach Leslie Frazier said. Since Freeman will miss at least one day of practice in a short week, the Vikings will "more than likely" turn to Christian Ponder to start Sunday, Frazier said.

Ponder was benched for Matt Cassel, but when Freeman signed as a free agent, the team rushed him to starting duty as soon as possible. He started Monday night against the Giants and turned in a dreadful performance.

On Tuesday the team discovered that he had concussion-like symptoms and will have to go through league-mandated tests. At a minimum, Freeman will not practice Wednesday, a big setback for a new quarterback trying to digest the offensive playbook.

"[Freeman] obviously won't be able to practice today, so he loses a day," Frazier said. "And when you consider the amount of time that he's missed, it probably is going to be difficult. And also, looking at the history of guys who have concussions on the short week that are able to get cleared for Sundays, we'll have to proceed as if he's not going to make it."
